The Canadian red and white maple leaf (枫叶) flag is officially called the National Flag of Canada. The Canadian flag shows a stylized red maple leaf with 11 points on a white background, with red borders down each side. The Canadian flag is twice as long as it is wide. The white square containing the red maple leaf is the same width as the flag.

    The red and the white used in the National Flag of Canada were proclaimed the official colors of Canada in 1921 by King George Ⅴ. Although the maple leaf did not have its official status as a symbol of Canada until the announcement (宣告) of the national flag in 1965, it had historically been used as a Canadian symbol, and was used in 1860 in decorations for the visit of the Prince of Wales to Canada. The 11 points on the maple leaf have no special significance.

    In the early days，the Royal Union Flag，or the Union Jack, was still flown in British North America. In 1925 and again in 1946, the Canadian Prime Minister Mackenzie King tried to get a national flag of Canada adopted, but failed. In 1964，Prime Minister Lester Pearson appointed a 15-member, all-party committee to come up with a design for a new flag. The committee was given six weeks to complete its task.

    The committee studied 2,000 submitted(提交的) designs as well as 3,900 that had been gathered as a result of the 1946 committee's study. Those designs with a chance of being accepted were given to the full committee for further study.

    The suggestion of a red and white single maple leaf design for the Canadian flag came from George Stanley, a professor at the Royal Military College. After a heated discussion, they finally decided on his suggestion.

How Room Designs Affect Our Work and Feelings

    Architects have long had the feeling that the places we live in can affect our thoughts, feelings and behaviors. But now scientists are giving this feeling an empirical（经验的，实证的） basis. They are discovering how to design spaces that promote creativity, keep people focused and lead to relaxation.

    Researches show that aspects of the physical environment can influence creativity. In 2007, Joan Meyers-Levy at the University of Minnesota, reported that the height of a room's ceiling affects how people think. Her research indicates that higher ceilings encourage people to think more freely, which may lead them to make more abstract connections. Low ceilings, on the other hand, may inspire a more detailed outlook.

    In additions to ceiling height, the view afforded by a building may influence an occupant's ability to concentrate. Nancy Wells and her colleagues at Cornell University found in their study that kids who experienced the greatest increase in greenness as a result of a family move made the most gains on a standard test of attention.

    Using nature to improve focus of attention ought to pay off  academically, and it seems to, according to a study led by C. Kenneth Tanner, head of the School Design & Planning Laboratory at the University of Georgia. Tanner and his team found that students in classrooms with unblocked views of at least 50 feet outside the window had higher scores on tests of vocabulary, language arts and maths than did students whose classrooms primarily overlooked roads and parking lots.

    Recent study on room lighting design suggests than dim（暗淡的） light helps people to loosen up. If that is true generally, keeping the light low during dinner or at parties could increase relaxation. Researchers of Harvard Medical School also discovered that furniture with rounded edges could help visitors relax.

    So far scientists have focused mainly on public buildings. "We have a very limited number of studies, so we're almost looking at the problem through a straw（吸管）," architect David Allison says. "How do you take answers to very specific questions and make broad, generalized use of them? That's what we're all struggling with."

    Today, I felt upset, I decided to take a walk even though I didn't know where I would go. The most extraordinary thing happened when I was out on this walk. I saw an old man sitting on a chair. He was a seller of second-hand shoes. He seemed so tired and nobody was buying his shoes.

    I wanted to give him something but I had not brought anything with me. Then, a little girl came toward him. I heard the child say, ''Grandfather, may I polish your shoes?" That old man took pity on her, smiled and he gave her a shoe to polish. The girl said, I polish the shoe because I need money to buy my brother a new school uniform. The old man answered, "Oh, little girl. Just stop doing this. Come with me and I will buy you a uniform.”

    Then they walked to a market (I followed behind) and he bought her a uniform. The girl was so happy. She said, Thank you so much for doing this." Then she left, leaving the old man smiling. He walked away from the market, but I stopped him.

    I whispered in his ear, "You are a hero! Thank you for your kindness!” As I walked away, I glanced back and I could see him still smiling. I was blown away by the kindness I had just seen. Someone who had so little himself was able to show such incredible generosity! Amazing!

    My own sadness had completely disappeared, chased away by the light of this kind act. I began realizing that I have a lot to be thankful for.

    On my first day of high school, I asked an eleventh-grader where my class was. And he told me it was "on the fourth floor, next to the pool." I found out five minutes later that we don't even have a fourth floor and there's no pool either! Besides that, I didn't have any trouble with the older kid.

    I think the biggest difference between middle and high school is the homework load (工作量) and size of the school. I went from maybe fifteen minutes of homework a night to several hours, so I had to learn how to make full use of time! Our class size is around 550, but joining in clubs, sports, music, and other activities at school makes it easier to get to know people in every grade.

    The best advice I can give about the years you spend in high school is to learn things for yourself, not just to get a good grade. There have been so many tests that I've prepared for the night before. I have gotten an A, and not remembered anything later. I've changed that this year, and I enjoy school so much more. Don't take easy classes just to have a simple year. If you have a choice between chemistry and sports, the first will prove to be a lot more useful!

    While drinking and smoking might be present in some middle schools, they're also around in high schools. I have a lot of friends who promised they'd never drink or smoke, but are now partying every weekend. If you have "fun" and spend your nights wasted instead of studying, you will regret it when you're applying for (申请) college. The "friends" who say you're a loser for not partying are really not your friends at all. It's hard to see your closest friends grow apart and go in different directions, but don't follow their footsteps. Create your own path in life and make your own decisions.

    Now in 2019, jazz music is an important part of Indianapolis' art culture. Jazz clubs around the city still host concerts with local jazz musicians like Rob Dixon and Joel Tucker. One of these clubs, the Chatterbox Jazz Club, still has live jazz seven nights a week.

    But the real history of jazz in Indy is much less simple. Along with the Avenue's culture, jazz music was gone from the streets for many years.

    Indiana Avenue was the heart of a neighborhood along the White River. It was a center for black music and live street music. The wealthy avoided this area. So it became a place that poorer families, including many African-American and immigrant (移民) families, moved to.

    Jazz prospered in the mix of American cultures around the Avenue in the 1930s and 1940s. But in the 1950s, things changed. After the war, there were projects to make the city beautiful and build a university nearby. Both of these seemed like good changes. However, the new university and buildings caused poorer families to have to leave the area. This destroyed the Indiana Avenue community - and with it, its jazz culture.

    After many years, Indianapolis remembered the value of its arts and music culture. It began to bring back lost cultures such as live music on the Avenue. To do so, it began to make new changes. The changes included repairing historic areas like the Avenue. Once again, the high living costs in these historic arts areas pushed low-income families out.

    Today there are several old-style jazz clubs where friends can meet up to remember the past or just enjoy a summer evening. It might seem at first that jazz is alive again, but there is a sad reality behind these jazz clubs: Modern Indy jazz is only a shadow (影子) of the lively culture that was once on Indiana Avenue.

Over the years, electronic commerce or e-commerce has grown rapidly. The rise of e-commerce large enterprises such as Amazon and Alibaba in the mid-90s changed the face of the retail (零售) industry. E-commerce may be thought of as an open, global marketplace or a digital version of mail-order catalogue (目录). Nearly every imaginable product and service is available through e-commerce dealings these days.

Many young entrepreneurs have dived into the e-commerce world, ambitious and hoping to succeed. Some, like Mitchell Zvagelskiy. Zvagelskiy is the co-founder of Scale Online, a fast-growing startup in California and runs several e-commerce stores. Zvagelskiy and his business partner began opening online stores and building a team to grow them, allowing the stores to earn as much as $100.000＋ in monthly revenue. Zvagelskiy owes his success to teamwork and his willingness to seize opportunity.

"Being able to do this all by the age of 20 is something I didn't expect and would not be able to do if I constantly listened to other people and just went the typical college then job route," he said. "Life can change fast if you change fast."

Thanks to the rapid success of his YouTube channel, Mitchell has been able to not only make great profit from his companies, but help others in starting and growing their own e-commerce stores too. "My meaning of success arises from my relationships with other people," he said. "By focusing on building strong relationships with others, I'm able to partner up and work with like-minded individuals in finding market opportunities and solving whatever problems people are facing."
